112dB is a music software company based in Utrecht, Netherlands, founded in 2005 by Claude Climer and Jules Vleugels. The company develops audio plugins for electronic music production and mixing, with a stated focus on tools that capture the warmth and character of vintage analog hardware while remaining straightforward to use.

The company's catalog spans several product families.

The Mikron series is a line of compact effects plugins covering reverb, delay, compressor, chorus, phaser, crusher, cascade, and orbiter, and the Big Blue series includes a dynamics compressor and limiter. The Cascade software synthesizer and the Jaws dynamic bitcrusher round out the instrument and effect offerings.
